Lose punches if you delete – The Wax Bar App Review

I don't normally write a review but I feel this earned one. This should not be linked to FB as login. Can you place change to email or a neutral log in? I have to keep the FB bc if not I can't use the app. I also recent had a stamp for one visit and now it's gone bc I had to delete app and re add bc it wasn't working. Can we just have stamp card then?
